Memory Systems Overview

The Cisco 7200 series and Cisco uBR7200 series memory systems are divided between the I/O controller and the network processing engine or network services engine. The network processing engine is available in five versions: the NPE-150, NPE-175, NPE-200, NPE-225, and NPE-300. The network services engine is available in one version: the NSE-1. The I/O controller is available with or without a Fast Ethernet port.

Note   Although still supported by Cisco Systems, the NPE-100 is no longer an orderable product as of May 2000.

Table 1 shows the network processing engine or network services engine options and restrictions for Cisco 7200 series and Cisco uBR7200 series routers, and Table 2 shows the I/O controller options and spare part numbers.

Installation Prerequisites

This section provides hardware and software requirements, and a list of parts and tools you need to remove main memory DRAM and SDRAM modules and Flash memory cards from Cisco 7200 series routers and Cisco uBR7200 series routers. This section also includes safety and ESD-prevention guidelines to help you avoid injury to yourself and damage to the equipment.

Parts and Tools

You need the following tools and parts to replace the main memory modules in the network processing engine or network services engine and the Flash memory cards in the I/O controller:

If you need additional equipment, contact a service representative for ordering information.

Software and Hardware Requirements

The NPE-300 is compatible with the Cisco 7200 VXR and Cisco uBR7246 VXR routers only. The NPE-300 is keyed to prevent insertion in the Cisco 7200 series routers (7202, 7204, and 7206) and the Cisco uBR7246 and Cisco uBR7223 universal broadband routers.

The NSE-1 is compatible only with the Cisco 7200 VXR routers.

We recommend that your boot helper image correspond to the minimum software release required for your platform. To upgrade your boot helper image, see the "Upgrading the Boot Helper Image" section.

Table 18 lists the recommended minimum Cisco IOS software release required to use the I/O controller in supported router platforms, and Table 19 and Table 20 list the recommended minimum Cisco IOS software release required to use the network processing engine or network services engine in supported router platforms.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Electrostatic Discharge Prevention

Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards or memory SIMMs or DIMMs are improperly handled and results in complete or intermittent failures.

The I/O controller and network processing engine or network services engine consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Handle the I/O controller and network processing engine or network services engine by their carrier edges and handle; never touch the printed circuit board or connector pins.

Figure 11 shows the location of a printed circuit board in a network processing engine or network services engine and an I/O controller metal carrier. Do not touch the printed circuit board when handling any of the components.


Figure 11: Handling the I/O Controller and the Network Processing Engine
or Network Services Engine


Handle SIMMs or DIMMs by the edges only. Avoid touching the memory modules, pins, or traces—the metal fingers along the connector edge of the SIMM or DIM. (See Figure 12.) Always wear a preventive antistatic strap whenever you handle SIMMs.


Figure 12: Handling a SIMM


Although the metal carrier helps to protect the I/O controller and the network processing engine or network services engine from ESD, wear a preventive antistatic strap whenever handling the I/O controller, network processing engine, or network services engine. Ensure that the strap makes good skin contact and connect the strap's clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.

If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution Make sure to tighten the captive installation screws on the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller (use a number 2 Phillips or a 3/16-inch flat-blade screwdriver). These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller are properly seated in the router midplane.

Following are guidelines for preventing ESD damage:

Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms (Mohm).

Ensuring Easy Access to the Router

If your Cisco 7200 series router or Cisco uBR7200 series router is installed in a standard 19-inch, 4-post rack or telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router. Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the following guidelines to ensure easy access to the rear of the router when it is installed in a rack. If the router is not installed in a rack, or if you already have clear access to the rear of the router, proceed to the "Removing and Replacing Main Memory DRAM and SDRAM" section.

Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:

Caution Make sure that at least one other person is available to support the front of the router as you slide it out from the rack and, if necessary, to continue to support it while you remove and insert the power supply, network processing engine or network services engine, or subchassis.

Removing and Replacing Main Memory DRAM and SDRAM

This section explains how to remove and replace the main memory modules on the network processing engines or network service engine. For the location of the memory module you are replacing, find the illustration that corresponds to your network processing engine or network services engine in the "Obtaining Documentation" section.

Before you can replace the main memory modules, you need to first complete the following:

After you have removed and replaced the DRAM or SDRAM, complete the procedure by doing the following:

Note   The procedures for removing and replacing the network processing engine or network services engine in Cisco 7200 series routers and in the Cisco AS5800 universal access server router shelf are the same. Therefore, the illustrations and procedures in the following sections apply to Cisco 7200 series routers and the Cisco AS5800 universal access server router shelf unless indicated otherwise.

The tasks for removing and replacing the network processing engine in Cisco uBR7200 series routers are slightly different from the platforms mentioned above. The differences are indicated in the following procedures.

Powering Down the Router

Warning This unit might have more than one power cord. To prevent the risk of electric shock, disconnect the two power cords before servicing the unit.

To power down a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps.

Note   Before powering down the router, use the copy running-config startup-config command to save the router's running configuration to nonvolatile memory.
Step 1   Facing the rear of the router, place the power switch on the power supply in the off (O) position. Repeat this action if a second power supply is installed in the router.

Step 2   Observe the following items:

This completes the procedure for powering down a Cisco 7200 series router or Cisco uBR7200 series router.

Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the power supply will enter a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the on (|) position. If you do not wait the full 90 seconds, the power supply will not restart.

Disconnecting Input Power

The following procedures explain how to disconnect input power from a Cisco 7200 series router or a Cisco uBR7200 series router.

If you have a DC-input power supply installed in your router, proceed to the "Disconnecting DC-Input Power" section. Otherwise, proceed to the next section, "Disconnecting AC-Input Power."

Disconnecting AC-Input Power

To disconnect AC-input power from a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps:

Step 1   Unplug the input power cable from the power source.

Step 2   Release the cable-retention clip.

Step 3   Unplug the other end of the input power cable from the power supply. (For a Cisco 7200 series router, see Figure 13. For a Cisco uBR7200 series router, see Figure 14.)


Figure 13: Disconnecting Power from a Cisco 7200 Series AC-Input Power Supply



Figure 14: Disconnecting Power from a Cisco uBR7200 Series AC-Input Power Supply—Cisco uBR7246 Shown


Step 4   Repeat Step 1 through Step 3 if a second power supply is installed.

This completes the procedure for disconnecting AC-input power from a Cisco 7200 series router or a Cisco uBR7200 series router.

Disconnecting DC-Input Power

To disconnect DC-input power from a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps.

Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Warning When installing the unit, the ground connection must always be made first and disconnected last.
Step 1   Turn off the power source and disconnect the -48V and +48V leads from the power source. You can leave the ground cable connected.

Step 2   Remove the restraints that secure the -48V, +48V, and ground leads from the power supply.

Note   The cable tie that accompanied your Cisco 7200 series DC-input power supply can be removed and replaced on the power supply without the use of a tool. If you secured the DC-input power supply leads to the power supply faceplate using a different type of cable tie, use a wire stripper to cut that cable tie from the power supply.
Figure 15: Removing the Strain-Relief Cover from a Cisco uBR7200 Series DC-Input Power Supply


Step 3   Disconnect the lead wires from the power supply.

Note   The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground, black is used for +48V (return), and red or white is used for -48V. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.

Figure 16: Disconnecting Power from a Cisco 7200 Series DC-Input Power Supply



Figure 17: Disconnecting Power from a Cisco uBR7200 Series DC-Input Power Supply


Step 4   Repeat Step 1 through Step 3 if a second power supply is installed.

This completes the procedure for disconnecting DC-input power from a Cisco 7200 series router or a Cisco uBR7200 series router.

Removing the Network Processing Engine or Network Services Engine

To remove the network processing engine or network services engine from a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps:

Note   The weight of installed power supplies in your Cisco 7200 series router might make it difficult to remove the network processing engine or network services engine. If you have difficulty, consider removing power supplies from the chassis and then removing the network processing engine or network services engine. See the "Removing and Replacing an AC-Input or DC-Input Power Supply" section for information on removing and replacing an installed power supply.

This note does not apply to Cisco uBR7200 series routers; the network processing engine is installed above the power supplies in Cisco uBR7200 series routers.
Step 1   Power down the router and disconnect its input power cable. See the "Powering Down the Router" section.

Step 2   Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 3   Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, loosen the two captive installation screws on the faceplate of the network processing engine or network services engine. (For the Cisco 7200 series, see Figure 18. For the Cisco uBR7200 series, see Figure 19.)

If the router is not installed in a standard 19-inch rack or in a telco-type rack, skip to Step 7. If the router is installed in a rack, determine if any permanent rack fixtures, such as a power strip, are obstructing access to the power supply. If a rack fixture is obstructing access to the power supply, proceed with Step 4.

Step 4   Using a 3/16-inch flat-blade screwdriver, loosen the four screws that secure the router to the front mounting strips of the rack.

Step 5   Position at least one person in front of the rack to support the front underside of the router.

Step 6   From the rear of the rack, carefully push the front of the router out of the rack until there is enough clearance to remove the network processing engine or network services engine.

Step 7   Grasp the network processing engine or network services engine handle and carefully pull the engine from its chassis slot.

Caution Handle the network processing engine or network services engine by the carrier edges and handle only; never touch the printed circuit board components or connector pins. (See Figure 11.)

Figure 18: Cisco 7200 Series Network Processing Engine Captive Screws and Handle



Figure 19: Cisco uBR7200 Series Network Processing Engine Captive Screws and Handle—Cisco uBR7246 Shown


Step 8   Place the network processing engine or network services engine on an antistatic surface with its printed circuit board components facing upward.

This completes the procedure for removing the network processing engine or network services engine.

Removing DRAM SIMMs

This section explains how to remove DRAM SIMMs that are installed on your network processing engine. To remove the installed SIMMs, complete the following steps:

Note   The NPE-175, NPE-225, and NPE-300, and NSE-1 use SDRAM DIMMS. See the "Removing SDRAM DIMMs" section for DIMM replacement instructions.
Step 1   Attach an ESD-preventive wrist strap between you and an unpainted router surface.

Step 2   Place the I/O controller or the network processing engine on an antistatic mat or surface (ensure that you are wearing an antistatic device, such as a wrist strap).

Step 3   Position the I/O controller or the network processing engine or so that the handle is away from you and the edge connector is toward you.

Step 4   Locate the SIMMs.

For the location of the memory module you are replacing, find the illustration that corresponds to your network processing engine in the "Obtaining Documentation" section.

Note   SIMMs installed in your system might look different from the SIMMS shown in the following illustrations.

Step 5   Release the spring clips from the SIMM that you want to remove, and release the SIMM from the socket. (See Figure 20.)


Figure 20: Releasing the SIMM Spring Clips


Step 6   When both ends of the SIMM are released from the socket, grasp the ends of the SIMM with your thumb and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only; avoid touching the memory module or pins, and the metal traces, or fingers, along the socket edge.

Step 7   Place the SIMM in an antistatic bag to protect it from ESD damage. You can use the SIMMs that you remove in compatible equipment.

Step 8   Repeat Step 4 through Step 7 for the remaining SIMMs.

This completes the SIMM removal procedure.

Installing New DRAM SIMMs

The DRAM SIMMs on the network processing engine are located in the following sockets:

Caution Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 12.)

To install memory SIMMs in the network processing engine, complete the following steps:

Step 1   With the network processing engine in the same orientation as the previous procedure (with the handle away from you and the edge connector toward you), install the first SIMM in the socket farthest from you. Then install the last SIMM in the socket closest to you.

Step 2   Remove a new SIMM from the antistatic bag.

Note   To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that your system initializes correctly at startup, DRAM bank 0 (socket U18 and U25, or U11 and U25) must contain no fewer than two SIMMs of the same type. You can also install two SIMMs of the same type in bank 1 (socket U4 and U12, or U42 and U52); however, bank 0 must always contain the two largest SIMMs.

Step 3   Orient the SIMM so its connector edge (the metal fingers) is down and the component side is facing you. (See Figure 21.)


Figure 21: Cisco 7200 Series Main Memory SIMM


Step 4   Hold the sides of the SIMM between your thumb and middle finger, with your forefinger against the far edge, opposite the connector edge. (See Figure 12.)

Step 5   Tilt the SIMM to approximately the same angle as the socket and insert the entire connector edge into the socket.

Caution When inserting SIMMs, use firm but not excessive pressure. If you damage a socket, you must return the I/O controller or the network processing engine to the factory for repair.

Step 6   Gently push the SIMM into the socket until the spring clips snap over the ends of the SIMM. If necessary, rock the SIMM gently back and forth to seat it properly.

Step 7   Repeat Step 2 through Step 6 for the remaining SIMMs.

Step 8   When all SIMMs are installed, check all alignment holes (two on each SIMM) and ensure that the spring retainer is visible. If it is not, the SIMM is not seated properly. If any SIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SIMM firmly back into the socket until the retainer springs snap into place.

This completes the SIMM replacement procedure. Proceed to the "Replacing the Network Processing Engine or Network Services Engine" section.

Removing SDRAM DIMMs

The procedures in this section are required only if you have an NPE-175, NPE-225, NPE-300, or NSE-1 and need to upgrade or replace the SDRAM DIMMs. On the NPE-175, NPE-225, and NSE-1, the SDRAM DIMMs are located in the following socket: U15. The two user-configurable SDRAM DIMMs on the NPE-300 are located in the following sockets: U45 and U44.

Note   The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet memory requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed configuration in the factory.

Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3 (see Figure 9). Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM in slot 3 can be zero.
Note   Use only SDRAM DIMMs supplied by Cisco Systems.

Use the following procedure to remove the existing DIMM:

Step 1   Turn off the system power and remove the network processing engine or network services engine from the system. (Follow the steps in the "Removing the Network Processing Engine or Network Services Engine" section.)

Step 2   Place the network processing engine or network services engine on an antistatic mat or pad and ensure that you are wearing an antistatic device, such as a wrist strap.

Step 3   Locate the DIMM and position the network processing engine or network services engine so that you are facing the DIMM module you want to remove.

Step 4   Open the DIMM socket tabs on the DIMM to release the DIMM from the socket. (See Figure 22.) The DIMM is under tension in the socket; therefore, the DIMM might be released from the socket with some force.


Figure 22: Opening DIMM Socket Tabs


Note   The SDRAM DIMM sockets on the NPE-175, NPE-225, and NPE-300 are parallel to the circuit board. They are not tilted at an angle.

Step 5   With the DIMM socket tabs open, grasp the ends of the DIMM between your thumbs and forefingers and pull the DIMM completely out of the socket. (See Figure 23.)


Figure 23: Removing the DIMM


Handle the edges of the DIMM only; avoid touching the memory module or pins, and the metal traces, or fingers, along the socket edge. (See Figure 24.)


Figure 24: Handling the DIMM


Caution To prevent ESD damage, handle the DIMM by the card edges only. Place a removed DIMM on an antistatic mat and store it in an antistatic container.

Step 6   Place the DIMM in an antistatic container to protect it from ESD damage.

This completes the DIMM removal procedure.

Installing New SDRAM DIMMs

The DIMM is a sensitive component that is susceptible to ESD damage. Handle the DIMM by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the DIMM). (See Figure 24.)

Caution To prevent ESD damage, handle the DIMM as shown in Figure 24.
Note   The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet memory requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed configuration in the factory.

Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3. (See Figure 9.) Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM in slot 3 can be zero.

With the network processing engine or network services engine in the same orientation as the previous procedure, install the DIMM in the DIMM socket as follows:

Step 1   Remove the new DIMM from its antistatic container.

Step 2   Hold the DIMM between your thumbs and forefingers. (See Figure 24.)

Note   The 64-MB DIMM should be facing component-side down.

Step 3   Slide the DIMM straight into the socket and insert the connector edge into the socket.

Note   The SDRAM DIMM sockets on the NPE-175, NPE-225, and NPE-300 are parallel to the circuit board. They are not tilted at an angle.
Caution When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you will have to return the NPE-300 to the factory for repair.

Step 4   Gently push the DIMM into the socket until the socket tabs close over the ends of the DIMM. (See Figure 25.) If necessary, rock the DIMM gently back and forth to seat it properly.


Figure 25: Inserting the DIMM


Step 5   When the DIMM is installed, check to see it is seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until first one and then the other socket tab moves into place.

This completes the DIMM replacement procedure.

Replacing the Network Processing Engine or Network Services Engine

To replace the network processing engine or network services engine in the router, complete the following steps.

Note   The NSE-1 is compatible only with the Cisco 7200 VXR series routers.
Note   The NPE-300 is compatible with the Cisco 7200 VXR and Cisco uBR7246 VXR routers only. The NPE-300 is keyed to prevent insertion in the Cisco 7200 series routers (7202, 7204, and 7206) and the Cisco uBR7246 and Cisco uBR7223 universal broadband routers.
Step 1   Ensure that the router is powered down and its input power cable is disconnected from the router and the power source. See the "Powering Down the Router" section.

Step 2   Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 3   Using both hands, grasp the network processing engine or network services engine by its metal carrier edges and orient the engine so that its printed circuit board components are upward (so that you can see the components). (See Figure 11.)

Caution Handle the network processing engine or network services engine by the carrier edges and handle only; never touch the printed circuit board components or connector pins.

Step 4   Align the left and the right edge of the network processing engine's or network services engine's printed circuit board between the network processing engine or network services engine slot guides. (For a Cisco 7200 series router, see Figure 26. For a Cisco uBR7200 series router, see Figure 27.)

Note   The NPE-300 and NSE-1carrier has metal posts that slide into grooves cut into the Cisco 7200 VXR network processing engine or network services engine slot. This keying feature does not alter the installation procedure for the NPE-300 or NSE-1. (See Figure 9.)
Caution Do not align the network processing engine's or network service engine's metal carrier between the slot guides. Doing so will damage components on the engine's printed circuit board as you slide the network processing engine or network services engine into its chassis slot.

Figure 26: Aligning the Network Processing Engine between the Slot Guides in
Cisco 7200 Series Routers



Figure 27: Aligning the Network Processing Engine between the Slot Guides in Cisco uBR7200 Series Routers—Cisco uBR7246 Shown


Step 5   Gently slide the network processing engine or network services engine all the way into its chassis slot until you feel the connectors make contact with the router midplane.

Step 6   Seat the network processing engine or network services engine in the router midplane by tightening its captive installation screws with a number 2 Phillips or a 3/16-inch flat-blade screwdriver.

Note   The network processing engine or network services engine is not fully seated in the router midplane until you tighten its captive installation screws.

Step 7   If you removed power supplies from the router, replace the power supplies. (See the "Removing and Replacing an AC-Input or DC-Input Power Supply" section when replacing an AC-input or DC-input power supply in a Cisco 7200 series router.)

Step 8   If you pushed the front of the router out of the rack, slowly guide the router back into the rack.

Step 9   Use a 3/16-inch flat-blade screwdriver to tighten the four screws that secure the router to the front mounting strips of the rack.

This completes the procedure for replacing the network processing engine or network services engine in a Cisco 7200 series router or a Cisco uBR7200 series router.

Reconnecting Input Power

The following procedures explain how to reconnect input power to a Cisco 7200 series router or a Cisco uBR7200 series router, power up the router, and verify a successful system boot.

Warning Read the installation instructions before you connect the system to its power source.

If you have a DC-input power supply installed in your router, proceed to the "Reconnecting DC-Input Power" section. Otherwise, proceed to the next section, "Reconnecting AC-Input Power."

Reconnecting AC-Input Power

To reconnect AC-input power to a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps:

Step 1   At the rear of the router, check that the power switch on the power supply is in the off (O) position.

Step 2   Slide the cable-retention clip up (Cisco 7200 series) or to the left (Cisco uBR7200 series), away from the AC receptacle, and plug in the power cable.

Step 3   Secure the cable in the power supply AC receptacle by sliding the cable-retention clip down (Cisco 7200 series) or to the right (Cisco uBR7200 series) until it snaps around the connector.

The cable-retention clip provides strain relief for the AC power cable. (For a Cisco 7200 series router, see Figure 28. For a Cisco uBR7200 series router, see Figure 29.)


Figure 28: Connecting AC-Input Power to a Cisco 7200 Series Router



Figure 29: Connecting AC-Input Power to a Cisco uBR7200 Series Router


Step 4   Plug the AC power supply cable into the AC power source.

Note   For a Cisco 7200 series router, each AC-input power supply operating at 120 VAC requires a minimum of 5A service.

For a Cisco uBR7200 series router, each AC-input power supply operating at 120 VAC requires a minimum of 7A service.

We recommend powering Cisco 7200 series routers and Cisco uBR7200 series routers from a 120 VAC, 15A receptacle United States (240 VAC, 10A international) at the power source.

Step 5   Repeat Step 1 through Step 4 if a second power supply is installed.

This completes the steps for reconnecting AC-input power to a Cisco 7200 series router or a Cisco uBR7200 series router. Proceed to the "Powering Up the Router" section.

Reconnecting DC-Input Power

To reconnect DC-input power to a Cisco 7200 series router or a Cisco uBR7200 series router, complete the following steps.

Note   The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground, black is used for +48V (return), and red or white is used for -48V. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.
Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Warning When installing the unit, the ground connection must always be made first and disconnected last.
Step 1   Ensure that the -48V and +48V leads are disconnected from the power source.

Step 2   At the rear of the router, check that the power switch on the power supply is in the off (O) position. (For a Cisco 7200 series router, see Figure 30. For a Cisco uBR7200 series router, see Figure 31.)


Figure 30: Connecting DC-Input Power to a Cisco 7200 Series Router



Figure 31: Connecting DC-Input Power to a Cisco uBR7200 Series Router


Step 3   If necessary, use a wire stripper to strip approximately 0.55 in. (14 mm) from the -48V, +48V, and ground leads. (See Figure 32.)


Figure 32: Stripping the DC-Input Leads


Note   The ground lead for the Cisco uBR7200 series DC-input power supply consists of a two-hole grounding lug that connects to an M5 grounding receptacle; you do not need to strip this ground lead.

Step 4   Insert the ground lead.

Step 5   Insert the stripped end of the +48V lead all the way into the +48V lead receptacle and tighten the receptacle screw using the same 3/16-inch flat-blade screwdriver. Repeat this step for the -48V lead.

Note   Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after you insert the lead into its receptacle, remove the lead, use the wire stripper to cut the stripped end of the lead, and repeat Step 3 through Step 5.

Step 6   After tightening the receptacle screw or nuts for the ground, +48V, and -48V DC-input leads, secure the leads to the power supply faceplate.

Note   For a Cisco 7200 series router, when securing the ground, +48V, and -48V DC-input leads to the power supply faceplate, leave a small service loop in the ground lead to ensure that it is the last lead to disconnect from the power supply if a great deal of strain is placed on all three leads. (See Figure 30.)
Note   A service loop is not required in the lead attached to the grounding lug on Cisco uBR7200 series routers because this lead is separate from the +48V and -48V leads and is secured by two M5 nuts to the M5 receptacles.

Step 7   For Cisco uBR7200 series routers, replace the strain-relief cover over the +48V and -48V leads, and using the 7-mm wrench or nut driver (or adjustable wrench), secure the cover to the strain-relief studs with the two M4 nuts. (See Figure 33.)


Figure 33: Replacing the Strain-Relief Cover on a Cisco uBR7200 Series DC-Input Power Supply


Step 8   Connect the ground, +48V, and -48V leads to the power source.

Note   For Cisco 7200 series routers, each DC-input power supply operating at -48 VDC in North America requires a minimum of 13A service. Each DC-input power supply operating at -60 VDC in the European Union requires a minimum of 8A service.

For Cisco uBR7200 series routers, each DC-input power supply rating is 14A, 700 volt amperes (VA).

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on all current carrying conductors.

Step 9   Repeat Step 1 through Step 8 if a second power supply is installed.

This completes the steps for connecting DC-input power to a Cisco 7200 series router or a Cisco uBR7200 series router.

Powering Up the Router

To power up a Cisco 7200 series router or a Cisco uBR7200 series router that has an installed AC-input or DC-input power supply, complete the following steps:

Step 1   Check for the following:

Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the power supply will enter a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the on (|) position. If you do not wait the full 90 seconds, the power supply will not restart.

Step 2   At the rear of the router, place the power switch on the power supply in the on (|) position. Repeat this step if a second power supply is installed in the router. The green OK LED on the power supply turns on.

Step 3   Listen for the fans; you should immediately hear them operating.

Step 4   During the boot process, observe the system's LEDs. The LEDs on most of the port adapters and the Cisco uBR7200 series cable modem cards go on and off in irregular sequence. Some may go on, go out, and go on again for a short time. On the I/O controller, the IO power OK LED comes on immediately.

Step 5   Observe the initialization process. When the system boot is complete (a few seconds), the network processing engine or network services engine begins to initialize the port adapters, Cisco uBR7200 series cable modem cards, and the I/O controller. During this initialization, the LEDs on each port adapter behave differently (most flash on and off). The enabled LED on each port adapter goes on when initialization is completed, and the console screen displays a script and system banner similar to the following:

Cisco Internetwork Operating System Software 
IOS (tm) 7200 Software (C7200-J-M), Version 11.1(17)CA [smith 100]
Copyright (c) 1986-1998 by cisco Systems, Inc.
Compiled Sun 21-Apr-98 04:10 by smith

If the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:

If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.

This completes the procedures for reconnecting input power and powering up the router. This also completes the procedure for removing and replacing memory SIMMs or DIMMs for the Cisco 7200 series routers and Cisco uBR7200 series routers.

Upgrading the Boot Helper Image

The boot helper image resides in Flash memory on the I/O controller and contains a subset of the Cisco IOS software. This image is used to boot your router from the network or to load Cisco IOS images onto the router. This image is also used if the system cannot find a valid system image.

Your boot helper image should correspond to the Cisco IOS release that is running on your router. When you upgrade your Cisco IOS software to the minimum required software release (see Table 18 and Table 19), we recommend that you also upgrade your boot helper image.

Note   The Cisco 7200 boot image in Cisco IOS Release 12.0 is oversized. If you need to upgrade the Cisco 7200 boot image, use the boot image in Cisco IOS release 12.05 in place of the boot image in Cisco IOS Release 12.0.
Note   Make sure you upgrade the boot helper image on any previously purchased I/O controller before attempting to boot a Cisco 7200 VXR or Cisco uBR7246 VXR router that has a newly installed NPE-175, NPE-225, or NPE-300.

To upgrade your boot helper image, obtain the most current boot helper image through Cisco Connection Online (CCO) and copy the new boot helper image to Flash memory on your router. For information on how to access CCO, see the "Cisco Connection Online" section. Follow the Software Center link under Service and Support. You need to get a login code from a Cisco representative to retrieve files from the Software Center.

To obtain a boot helper image from CCO and upgrade your bootflash, do the following:

Step 1   Download the boot helper image from CCO to a Trivial File Transfer Protocol (TFTP) server.

Step 2   Reformat the Flash memory on your router as follows:

router# format bootflash:

Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "bootflash:".  Continue? [confirm]
Formatting sector ...   
Format of bootflash:complete
Note   Reformatting Flash memory erases the current Flash memory contents.

Step 3   Copy the boot helper image from the TFTP server to Flash memory as follows:

router# copy tftp bootflash:

Address or name of remote host []? biff
Source filename []? c7200-boot-mz.120-5.S
Destination filename [c7200-boot-mz.120-5.S]?

This completes the procedure for upgrading your boot helper image. For more detailed instructions on loading and maintaining system images and microcode, including boot helper images, refer to the Configuration Fundamentals Configuration Guide, which is available on CCO.

Using the Flash Memory Cards

The following sections provide general instructions for installing, reformatting, and copying images onto and between the Flash memory cards that reside in the I/O controller PC Card slots.

Installing and Removing a Flash Memory Card

The I/O controller has two PC Card slots: slot 0 (lower) and slot 1 (upper). (See Figure 34.) To install a Flash memory card in either PC Card slot, complete the following steps.

Note   For procedures that explain how to remove and replace the Flash Disk in an I/O controller, refer to the Using the Flash Disk document that accompanies every Flash Disk shipped from the factory.
Note   To avoid potential problems when you insert spare Flash memory cards in your router, we recommend that you reformat all of your Flash memory cards using the recommended minimum Cisco IOS software release for your platform during your regularly scheduled service times. (See Table 18 on page 22.)

The "Reformatting a Flash Memory Card" section contains instructions on how to reformat a Flash memory card.
Step 1   Connect an ESD-preventive strap between you and an unpainted chassis surface.

Step 2   Orient the Flash memory card so that its connector end faces the appropriate slot. (See Figure 34a.)

Step 3   Carefully guide the card into the slot until it mates with the slot's connector, and the ejector button for the slot pops out toward you. (See Figure 34b.)

Note   Flash memory cards do not insert all the way into the PC Card slots on the I/O controller; the end of the card protrudes from the I/O controller faceplate. Do not attempt to force the card past this point.

Some older Flash memory cards might have foil tape attached to the outside edge of the card. If you insert one of these Flash cards into the upper PC Card slot (slot 1) of an I/O controller installed in a Cisco uBR7200 series, it might be difficult to remove the card. You should either use a new Flash memory card that does not have the foil tape, remove the foil tape from the older Flash memory card, or if necessary, use small pliers to remove the Flash memory card.

This completes the procedure for installing a Flash memory card in either PC Card slot.

To remove a Flash memory card from either PC Card slot, complete the following steps:

Step 1   Press the ejector button on the slot. (See Figure 34c.)

Step 2   Grasp the card and pull it from the slot.

Step 3   Place the card in an antistatic bag.


Figure 34: Installing and Removing a Flash Memory Card


Reformatting a Flash Memory Card

Depending on the circumstances, you might need to use a Flash memory card or Flash Disk from another system to copy images or to back up configuration files; however, you cannot boot from a Flash memory card or Flash Disk that was formatted on another type of system. You must reformat the card before you can use it as a boot source.

The procedure for reformatting a Flash memory card and a Flash Disk is similar; however, this section is specific to Flash memory cards.

Note   For procedures that explain how to reformat the Flash Disk, refer to the Using the Flash Disk document that accompanies every Flash Disk shipped from the factory.
Note   To avoid potential problems when you insert spare Flash memory cards in your router, we recommend that you reformat all of your Flash memory cards using the recommended minimum Cisco IOS software release for your platform during your regularly scheduled service times. (See Table 18 on page 22.)
Caution The following formatting procedure erases all information on the Flash memory card. To prevent the loss of important data that might be stored on a Flash memory card, proceed carefully. If you want to save the data on a Flash memory card, copy the data to a server before you format the card.

The formatting procedure assumes the following:

Use the following procedure to reformat a Flash memory card:

Step 1   Insert the Flash memory card into slot 0. (If slot 0 is not available, use slot 1.) See the "Installing and Removing a Flash Memory Card" section.

Step 2   Copy all the files on the Flash memory card to a TFTP server or a secondary Flash memory card. The following example is for copying files to a TFTP server:

Router> enable

Password: <password>
Router# copy slot0:image.name tftp

Enter destination file name [image.name]: image.name 
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
CCCCCCCCCCCCC

Address or name of remote host [tftp.server.name]? tftp.server.name

Router#

Step 3   To reformat the Flash memory card, use the format slot0: (or format slot1:) command as follows:

Router# format slot0:

All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): MyNewCard

Formatting sector 1
Format device slot0 completed
Router#

Step 4   Copy the files you saved to the TFTP server back to the Flash memory card as follows:

Router# copy tftp slot0

Enter source filename: image.name

20575008 bytes available on device slot0, proceed? [confirm]
address or name of remote host [tftp.server.name]? tftp.server.name

The Flash memory card is now reformatted and ready to use.

Copying a Bootable Image onto a Flash Memory Card

Once you have reformatted your Flash memory card or Flash Disk, you can copy a bootable image onto it. The procedure for copying an image onto a Flash memory card or Flash Disk is based on the following assumptions:

The procedure for copying a bootable image onto a Flash memory card and onto a Flash Disk is similar; however, this section is specific to Flash memory cards.

Note   For procedures that explain how to copy a bootable image onto a Flash Disk, refer to the Using the Flash Disk document that accompanies every Flash Disk shipped from the factory.

Use the following procedure to copy a bootable file (called new.image in the examples) onto the Flash memory card:

Step 1   Boot the router and allow it to initialize.

Step 2   Insert a Flash memory card into slot 0 (use slot 1 if slot 0 is not available) and reformat the card using the procedure in the "Reformatting a Flash Memory Card" section. Then proceed to Step 3.

Note   You cannot boot from a Flash memory card that was formatted on another type of system. You must reformat the card to use it as a boot source. To avoid potential problems when you insert Flash memory cards in your router, we recommend reformatting all of your Flash memory cards on a router running the Cisco IOS software release recommended for your platform (see Table 18 and Table 19) during your regularly scheduled service times.

Step 3   Using the following series of commands, copy the new image (new.image in the following example) to the Flash memory card:

Router> enable

Password:
Router# copy tftp:new.image slot0:new.image

20575008 bytes available on device slot0, proceed? [confirm]
address or name of remote host [1.1.1.1]?

CCCCCC
Router#
Note   In the preceding example, the exclamation points (!!!) appear as the file is downloaded, and the "C" characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the Flash memory card.

Step 4   Use the following series of commands to designate the file new.image (in the Flash memory card slot 0) as the default boot helper image and reboot the router:

Router# configure terminal

Router(config)# no boot system

Router(config)# boot system flash slot0:new.image

Router(config)# Ctrl-Z

Router# copy running-config startup-config

Router# reload

When the system reloads, it will boot the new.image file from the Flash memory card.

Copying Bootable Images Between Flash Memory Cards

As future releases of Cisco IOS images become available, you will receive these images either as a file booted from a network server, a file on floppy disk, or a file on a Flash Disk or Flash memory card.

The procedure for copying bootable images between Flash memory cards and between Flash disks is similar; however, this section is specific to Flash memory cards.

Note   For procedures that explain how to copy bootable images between Flash disks, refer to the Using the Flash Disk document that accompanies every Flash Disk shipped from the factory.

The following scenario describes how to use a newly released image on a Flash memory card in a system that has an older image on a Flash memory card in slot 0 and a default boot helper image in the onboard Flash memory.

For this scenario, the filenames are as follows:

You will copy the new image from the new Flash memory card onto the Flash memory card that contains the old image.

Note   The scenario assumes that the new image will fit on the Flash memory card in slot 0, alongside the old image. If there is not enough available space, use the delete command to delete files from the Flash memory card to make sufficient room for the new image; however, do not delete the image.old file. Then use the squeeze command to remove these deleted files from the Flash memory card. If, after you have deleted files and used the squeeze command, the two files cannot coexist on the Flash memory card in slot 0, remove this card (place it in an antistatic bag and store it in a safe place), and insert the new Flash memory card (with the file new.image) in slot 0. Proceed to Step 5 and use the command boot system flash slot0:new.image to designate the file new.image as the default boot helper image.
Step 1   Boot the router. By default, the file boot.image is used.

Step 2   Enable the router as follows:

Router> enable

Password:
Router#

Step 3   Insert the new Flash memory card in slot 1.

Step 4   Use the following command to copy the file new.image in slot 1 to the Flash memory card in slot 0, only if there is enough memory space for the two images to coexist. If there is not enough memory space, proceed to Step 5.

Router# copy slot1:new.image slot0:new.image
Note   You can also enter the preceding command as copy slot1:new.image slot0:.

Step 5   Use the following series of commands to designate the file new.image (which is on the Flash memory card in slot 0) as the default boot helper image and reboot the router:

Router# configure terminal

Router(config)# no boot system

Router(config)# boot system flash slot0:new.image

Router(config)# Ctrl-Z

Router# copy running-config startup-config

Router# reload

When the system reloads, it will boot the file new.image from the Flash memory card in slot 0.

Removing and Replacing an AC-Input or DC-Input Power Supply

The weight of power supplies installed in a Cisco 7200 series router might make it difficult for you to pull the network processing engine or network services engine from its chassis slot. If this is the case, consider removing installed power supplies from the chassis and then removing the network processing engine or network services engine.

The following sections explain how to remove and replace an AC-input or a DC-input power supply in a Cisco 7200 series router.

Note   The network processing engine is installed above the power supplies in a Cisco uBR7200 series router. You do not need to remove the power supplies from a Cisco uBR7200 series router to pull the network processing engine from its chassis slot.
Caution Do not mix AC- and DC-input power supplies in the same router.

Removing a Power Supply

The steps for removing an AC-input or DC-input power supply from a Cisco 7200 series router are the same. The two power supplies share the same dimensions and faceplates, except for the AC-input receptacle on the AC-input power supply and the DC-input lead receptacles on the DC-input power supply.

To remove an AC-input or DC-input power supply from a Cisco 7200 series router, complete the following steps:

Step 1   Ensure that the power switch on the power supply is in the off (O) position and input power is disconnected from the power supply and its power source. (See the "Powering Down the Router" section.)

Step 2   Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the faceplate of the power supply. (See Figure 35.)

If the router is not installed in a standard 19-inch, 4-post or telco-type rack, skip to Step 6. If the router is installed in a rack, determine if any permanent rack fixtures, such as a power strip, are obstructing access to the power supply. If a rack fixture is obstructing access to the power supply, proceed to Step 3.


Figure 35: Power Supply Captive Installation Screws and Handle—Cisco 7200 Series
AC-Input Power Supply Shown


Step 3   Using a 3/16-inch flat-blade screwdriver, loosen the screws that secure the router to the front mounting strips of the rack.

Step 4   Position at least one person in front of the rack to support the front underside of the router.

Step 5   From the rear of the rack, carefully push the front of the router out of the rack until there is enough clearance to remove the power supply.

Step 6   Grasp the power supply handle and pull the power supply from the router.

Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200 series chassis with a single power supply, the power supply filler plate must remain in the power supply adjacent to the installed power supply. Do not remove this filler plate from the router unless you intend to install a redundant power supply.

Step 7   Repeat Step 1 through Step 6 for the other installed power supply (if present).

This completes the procedure for removing an AC-input or DC-input power supply from a Cisco 7200 series router. Proceed to the following section, "Replacing a Power Supply."

Replacing a Power Supply

To replace an AC-input or DC-input power supply in a Cisco 7200 series router, complete the following steps:

Step 1   Make sure the power switch on the power supply is in the off (O) position. (See  Figure 13 or AC and Figure 16 for DC.)

Step 2   Grasp the power supply handle with one hand and place your other hand underneath the power supply for support. (See Figure 36.)


Figure 36: Holding the Power Supply—Cisco 7200 Series AC-Input Power Supply Shown


Step 3   Align the power supply with the power supply bay.

Step 4   Slide the power supply completely into the power supply bay until its faceplate is flush with the router's rear panel.

Caution When inserting a power supply into the router, do not use unnecessary force; slamming the power supply into the bay can damage the connectors on the rear of the supply and on the midplane.

Step 5   Seat the power supply in the router by tightening its captive screws with a number 2 Phillips or a 3/16-inch flat-blade screwdriver.

Note   The power supply is not fully seated in the router midplane until you tighten its captive installation screws.

Step 6   Repeat Step 1 through Step 5 for a second power supply (if present).

Step 7   If there is no second power supply, replace the filler plate on the empty power supply bay. Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, tighten the filler plate's captive screws.

Step 8   If you pushed the router out of the rack, slowly guide the router back into the rack.

Step 9   Use a 3/16-inch flat-blade screwdriver to tighten the screws that secure the router to the front mounting strips of the rack.

Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200 series routers with a single power supply, the power supply filler plate must remain in the power supply adjacent to the installed power supply. Do not remove this filler plate from the router unless you intend to install a redundant power supply.

This completes the procedures for replacing an AC-input or DC-input power supply in a Cisco 7200 series router.
